CAUTION!
NOTE: Do not operate the unit without the proper filter or with
a less effective filter. The heat exchange coils inside the unit
could become clogged, resulting in a loss of effectiveness
and/or efficiency and may require disassembly to clean.
7.1 Air Filter
SAKURA Dry-Boy ships with a standard MERV-11 65%
1" pleated fabric filter and a 1/4" aluminum framed pre-filter

reduce dehumidifier capacity and efficiency and may cause the
compressor to cycle on and off unnecessarily.

visibly dirty. See cleaning instructions below.
The 1/4" washable pre-filter
should not to be discarded.
Inspect the pre-filter for debris,
dirt, or other obstructions at
the same time the 1" pleated
fabric filter is checked. Wash the
1/4" pre-filter every time the 1"
pleated fabric filter is replaced. To
clean the 1/4" pre-filter, remove
filter from the unit, rinse the 1/4"
pre-filter in water with the water
flowing through the aluminum
support mesh side. Refer to
Figure 11. Allow the filter to dry
completely before reinstalling.
Reinstall the filters per the
instructions below or on the tag
located on the 1/4" pre-filter.

in improper function of the dehumidifier and cause premature
filter wear.
